Silurian Lands and Seas is the only up-to-date synthesis of plate tectonics, paleogeography, biotic distribution, and geologic history of the 20 million year-long Silurian geologic period. In-depth contributions by 44 specialists recreate the geologic history of this important interval in earth history in eleven important regions world-wide. A product of the Silurian Subcommission, Silurian Lands and Seas is a profusely illustrated volume that will be a major addition to college and university libraries. It will be used in earth history research and courses for undergraduates, graduate students, and professionals in paleogeography, tectonics, stratigraphy, sedimentology, paleontology, and natural resources.
